基于多征兆信息融合理论的转子故障诊断

Based on Multi-symptom Information Fusion Theory Rotor Fault Diagnosis

在研究了Dempster-shafer证据理论及其算法的基础上,提出了一种基于多征兆信息融合理论的故障诊断方法。以转子故障为例,论述了该方法的实施过程。结果表明,多征兆信息的信息融合诊断方法具有良好的稳定性和容错性,提高了转子故障诊断的准确性和可靠性。

The conception incorporated multi-sensor data fusion with Dempster-shafer evidential theory was discussed in brief.Taking the rotor fusion as an example,the imple-menting process of this diagnosis method is presented in detail.The diagnosis result indicates that the multi-symptom information fusion has the stability and the ability of fault tolerance,and can improve the accuracy and reliability of fault diagnosis of diesel engine effectively.
